POLICE are today hunting five men of “African appearance” who lured a nurse into a park with fake cries for help then beat her unconscious and sexually abused her.

IG/GETTY German police are investigating a sex assault in a Hamburg park

Officers in the German city of Hamburg are appealing for witnesses following the brutal attack on the female hospital worker, who was unconscious for so long that she developed hypothermia.

The 28-year-old was walking to her car from work at the nearby Asklepios hospital when she apparently heard cries for help coming from a nearby park.

But when she rushed into the dark space to offer assistance she was set upon by five men and was beaten unconscious and mugged.

Police said there was also evidence that the gang had sexually abused their victim, and that they were not talking German to one another during the attack.

There is nothing at this stage to suggest that the men involved in the horrific assault were recently arrived refugees.

Officers said the young woman was left unconscious in the park by her attackers, and called the emergency services herself when she awoke several hours later.

When paramedics arrived she was suffering from hypothermia and some of her clothes had been torn from her body, according to the German tabloid Bild.

Police are appealing for witnesses to the horrific attack, which took place in the Lohmühlenpark, and have released descriptions of the men based on the woman’s recollections.

She described all five of them as being of “African appearance”. Four of them were between 20 and 30 years old, about six feet tall and were wearing dark clothes.

The fifth was older, probably around 40, was taller than the others and had distinctive “bright dots” on both cheeks. He also had a thicker figure and was wearing a green or turquoise shirt with stripes of glitter around the chest area, and a dark jacket.

Germany has been rocked by a number of sex attacks, some carried out by recently arrived refugees, in the last year since the horrific mass assaults and rapes in the city of Cologne on New Year’s Eve 2015.
